please help with this assignement i have already written something but it does not produce an output as intended please update the code that i have written.

For this assignment you are required to design an algorithm or pseudocode and then develop a Java program to read a series of data from an input file and process the data for a group of people. Your program calculates the interest and print the details to the monitor, refer to the sample below. Terminate the program when the end of the file is reached. Prompt user for the data file name, open, read and process the data. Refer to the sample file below for the file organization. In this assignment there is no need to verify data. Your program will calculate the interest paid on the amount of money on deposit based on the number of years it has been on deposit amount, the associated interest rate, and number of times the interest is paid per year. The interest rate to be used on the deposit is based on the following schedule:

 Time on Deposit Interest Rate >= 5 years 4.5% Less than 5 and >=4 years 4% Less than 4 and >=3 years 3.5% Less than 3 and >=2 years 2.5% Less than 2 and >=1 years 2% Less than 1 year 1.5% 

The program will use the read code to determine the number of times compound interest is calculated and paid per year.

 Code Number of times calculated A 4 B 2 C 1 D 12 E 365 

Compute the interest using the following formula: ----> A = P(1+ r/n)^nt P = principal amount (the initial amount you borrow or deposit) r = annual rate of interest (as a decimal) t = number of years the amount is deposited or borrowed for. A = amount of money accumulated after n years, including interest. n = number of times the interest is compounded per year

Example:

An amount of $1,500.00 is deposited in a bank paying an annual interest rate of 4.3%, compounded quarterly. What is the balance after 6 years?

Solution: Using the compound interest formula, where P = 1500, r = 4.3/100 = 0.043, n = 4, t = 6. Therefore, Calculation: A = 1500(1+0.043/4)^(4 * 6) So, the balance after 6 years is approximately $1,938.84. Requirements:

• Name the class CalcInterest and save it in a Java file named CalcInterest.java
• Prompt user for file names
• include minimum of 4 Methods, more is OK
• Use good variable names
• Must use arrays, assumes there are maximum 20 customers, but could be less. Make the arrays of size 20.

Output

Display the original deposit, years on deposit, the interest earned and the new balance (initial deposit +interest) in a table form. Your program will prompt user for the name of input and output files and will process all the data.

Refer to the samples below for input file organization and the output format to the monitor and the output file.

Input file format:

Name Amount deposited Years Code 

Input file sample:

Joseph Cardian III 1800 6 A Nancy Brown 6780 10 a 

Sample output 1

Enter Input File name: assign3.txt Enter Output File name: out.txt Name Years Deposit Amount Interest Earned New Balance Joseph Kardian III 6 $1500.00 $461.99 $1961.99 Nancy Brown 10 $6780.00 $3835.32 $10615.32 

Sample output 2 (Printed to the monitor only)

Enter File name: abc.txt Could not open file. Program terminated. 

Sample output 3 (Printed to the monitor only)

Enter File name: blank.txt There was no data in the file. Program terminated.

temp.txt is as follows:
